Air enclosurewith side cushioning function

Abstract

An air enclosure with a side cushioning function comprises two outer films stacked together vertically and two inner films disposed between the outer films. An air filling passageway is formed between the inner films and a plurality of air filling permissible air cylinders and at least one air filling impermissible air cylinder are formed between the outer films by means of hot sealing, and air entering passageways used for communicating the air filling passageway with the air filling permissible air cylinders are formed by adhering the inner films by means of hot sealing. When air in the air filling passageway enters the air entering passageways to cause the plurality of air filling permissible air cylinders to be filled with air and expanded, the air filling impermissible air cylinders maintain flat and a fall of level is generated between the air filling permissible and impermissible air cylinders to enable the air filling permissible air cylinders to wrap a different size or dimension of article and provide the article with the side cushioning function.

1 . An air enclosure with a side cushioning function, comprising:
 two outer films, stacked together vertically;   two inner films, disposed between the outer films;   an air filling passageway, being a space formed by adhering the inner films to each other by means of hot sealing;   a plurality of air filling permissible air cylinders, disposed at one end of the air filling passageway and respectively being an air storable space formed by adhering the outer films to each other by means of hot sealing;   at least one air filling impermissible air cylinder, disposed at one end of the air filling passageway and formed by adhering the outer films to each other by means of hot sealing; and   at least one air entering passageway, communicated with the air filling passageway and the air filling permissible air cylinder and formed by adhering the inner films to each other by means of hot sealing;   wherein, after the air filling permissible air cylinders are filled with air and expanded, the air filling impermissible air cylinders maintain flat and a fall of level is generated between the air filling permissible and impressible air cylinders, the air enclosure is bended along the air filling impermissible air cylinders to enable the air filling permissible air cylinders to wrap an article and provide the side cushioning function.   
   
   
       2 . The air enclosure according to  claim 1 , wherein the air filling permissible air cylinder comprises at least one node, and the air filling permissible air cylinder is bended along the nodes. 
   
   
       3 . The air enclosure according to  claim 1 , wherein the air filling permissible air cylinder is positioned at one side of the air filling permissible air cylinder. 
   
   
       4 . The air enclosure according to  claim 3 , wherein the air filling impressible air cylinder is positioned between the air filling permissible air cylinders. 
   
   
       5 . The air enclosure according to  claim 4 , wherein the air filling permissible air cylinders forms a flexible area used for allowing a distance between the air filling permissible air cylinders to be adjusted. 
   
   
       6 . The air enclosure according to  claim 1 , wherein a middle section of the air filling impermissible air cylinder is not allowed to fill with air and provided with tiny tubes connected with upper and lower sections thereof to allow the upper and the lower sections of the air filling impermissible air cylinder to be filled with air yet. 
   
   
       7 . The air enclosure according to  claim 1 , wherein parts of the air entering passageways are sealed by means of hot sealing to cause air in the air filling passageway not to enter the air filling impermissible air passageways. 
   
   
       8 . An air enclosure with a side cushioning function, comprising:
 two outer films, stacked together vertically;   two inner films, disposed between the outer films;   an air filling passageway, being a space formed by adhering the inner film to one of the outer films by means of hot sealing;   a plurality of air filling permissible air cylinders, disposed at one end of the air filling passageway and respectively being an air storable space formed by adhering the outer films to each other by means of hot sealing;   at least one air filling impermissible air cylinder, disposed at one end of the air filling passageway and formed by adhering the outer films to each other by means of hot sealing; and   at least one air entering passageway, communicated with the air filling passageway and the air filling permissible air cylinder and formed by adhering the inner film to one of the outer films by means of hot sealing;   wherein, after the air filling permissible air cylinders are filled with air and expanded, the air filling impermissible air cylinders maintain flat and a fall of level is generated between the air filling permissible and impressible air cylinders, the air enclosure is bended along the air filling impermissible air cylinders to enable the air filling permissible air cylinders to wrap an article and provide the side cushioning function.   
   
   
       9 . The air enclosure according to  claim 8 , wherein the air filling permissible air cylinder comprises at least one node, and the air filling permissible air cylinder is bended along the nodes. 
   
   
       10 . The air enclosure according to  claim 8 , wherein the air filling permissible air cylinder is positioned at one side of the air filling permissible air cylinder. 
   
   
       11 . The air enclosure according to  claim 10 , wherein the air filling impressible air cylinder is positioned between the air filling permissible air cylinders. 
   
   
       12 . The air enclosure according to  claim 11 , wherein the air filling permissible air cylinders forms a flexible area used for allowing a distance between the air filling permissible air cylinders to be adjusted. 
   
   
       13 . The air enclosure according to  claim 8 , wherein a middle section of the air filling impermissible air cylinder is not allowed to fill with air and provided with tiny tubes connected with upper and lower sections thereof to allow the upper and the lower sections of the air filling impermissible air cylinder to be filled with air yet. 
   
   
       14 . The air enclosure according to  claim 8 , wherein parts of the air entering passageways are sealed by means of hot sealing to cause air in the air filling passageway not to enter the air filling impermissible air passageways.
